Climate change, in terms of both scale and potential impact, is a reality that threatens the most basic human needs, from food and water to human settlement patterns. While it is difficult to establish a direct causal link between climate change and migration, one of the major consequences of the changing environment will be on people’s livelihood. Sudden or progressive changes to the environment, such as rising sea levels, water scarcity, decrease in crop yields and an increase in extreme weather events will have an effect on people’s lives and living conditions. When people can no longer gain a secure livelihood, migration may be the only option.
